CUSHION-HEEL.

Application filed. February 7, 1920. Serial No. 356,815.

I To all whom it may concern:

Be it known that I, ALBERT H. AMMANN, a citizen of the United States,residing at Peotone, in the county of Will and State of Illinois, haveinvented new and useful Improvements in Cushion-Heels, of which theollowing is a specification.

This lnvention relates to cushion heels consisting of a rubber block orplate which is nailed or otherwise fastened to the bottom of the shoe,and the object of the invention is to provide a heel of this kind havinga greater degree of resiliency than the ordinary solid rubber heel, andwhich also assists the wearer when walking, as well: as

tending to correct improper walking of the of the heel; Fig. 2 is asection thereof on the line 2-2 of Fig. 1; Fig. 3 is a plan view of aheel showing a modification; Fig. 4 is a cross section on 'the line 4-4of Fig. 3, and Fig. 5 is a cross section showing a heel simi lar to thatin Fig 4 but having cavities in- .clined in an opposite direction.

Referring specifically to the drawing and more particularly to Figs. 1and 2, 10 denotes a rubber heel of conventional contour, and havingholes 11 through which are adapted to be passed nails, screws or otherdevices for fastening the heel in place on the boot or shoe. The heel isformed with a plurality of elongated and parallel internal cavities 12which are obliquely positioned between the top and bottom of the heel.

These cavities are inclined at an angle of about 45 degrees to the planeof the top and bottom of the heel, and they lean or are inclined fromthe perpendicular in the direction of the rear of the heel.

The cavities 12 add to the elasticity of the heel and hence increase thecushioning efi'ect, and owing to the obliquity of the cavities,

the latter assist the person in walking. When the persons weight bearsdown on the heel and compresses the same, and the weight is thenremoved, the tendency of the heel to resume its normal shape is in adirectlon to force the foot forward, thus assist 111%:13116 person inwalking.

igs. 3 and 4 illustrate a difierent arrangement of cavities 12. Here,the cavities are inclined from the perpendicular in a directiontransversely of the heel. By this arrangement the tendency to turn theheel outwardly is eliminated or reduced to a minimum, and the walk ofthe person is corrected, the heel being pulled inwardly. Fig. 5 showsthe cavities inclined in the proper direction for a heel to be worn onthe right foot for those who wear their heels ed on the outside, thuscausing a correction in the walk opposite to that resulting from theinclination of the cavities as shown in Fig. 4.

The cavities are ,preferably formed by cutting a series of horizontalpassages through the heel, and plugging their ends with rubber blocksproperly cemented. Plugging of the passages may be dispensed with,however, without impairing the efii ciency of the heel.

While the inventionhas been illustrated and described in connection withheels, it will be apparent that the principle is readily applicable tosoles as ',lwell, without departing from the spirit and scope of theinvention.

1. A rubber heel comprising a body having a series of elongated andparallel internal cavities which are inclined from the perheel.

2. rubber heel comprising a body havties which are inclined from theperpendicular in a direction transversely of the heel.

In testimony whereof I afix my -signature.
